Disable "Calculate Tax" button on AP Invoice forms.

Hi Experts,

I am wondering if you could tell me a way to disable/hide the "Calculate Tax" button on AP Invoice forms. We want the personlizations to be the last option.

Also, we have disabled the  "Allow Tax Applicability" check box for AP Standard Invoices as per note: 811272.1

Could you please explain if the "Calculate Tax" button would do anything or thrown an error if users click on it by mistake?

Please let me know.

Thanks,

Aditya
